Twilight Horizon provides information about the new Triple AAA megacorporation in the Shadowrun setting, Horizon, additionally Las Vegas is updated for the Sixth World of Shadowrun and there are many, many plot hooks and adventure ideas. If you want to incorporate Horizon as a major player in your Shadowrun campaign (or to have your ‘runners visit Vegas) this product will prove a worthwhile resource.

Twilight Horizon begins with a short piece of fiction and then moves into the meat of the book, starting with an overview of Horizon Corporation, the youngest of the “Big Eight” megacorps that dominate the Shadowrun setting. For a book focused on Horizon, the description of the corporation is very short, only seven pages (though various points are expanded upon later in the book) but gives a basic overview of the way Horizon works especially the intra-corporation ‘consensus’ that guides how the corporation acts.

Vegas gets a few more pages (21) and provides a good lay of the land for action taking place there. It’s a crazy town. The bulk of the product is fifteen semi-linked adventure frame works, primarily aimed at experienced runners, that chronicle Horizon’s continuing evolution among the megacorps including one that takes places at the Sixth World’s evolution of the Burning Man festival! A wide variety of NPCs are provided for the various adventures and other Horizon-based adventures. Lastly, some updated rules for simsense and persona fix chips, both businesses that Horizon is deeply invested in.

Overall, a useful game master’s resource for the evolving world of Shadowrun if Horizon or Las Vegas is likely to be involved in your campaign.
